There is a hardcode limit to grow a collection but it looks like it wasn't documented - feel free to open a ticket in JIRA.

Our form is submitting values for a list of > checkboxes like this: > > selected[0]: true > selected[1]: true > selected[2]: false > selected[3]: true > ... > selected[499]: false > selected[500]: true > > This corresponds to a variable in our action that looks like: > private List<Boolean> selected; > //getter() and setter() here. > > The issue we’re having is that when we get into our action code, the > “selected” list only ever has the first 256 items that we submitted. I > manually pulled the list of parameters out of the ActionContext, and they > were all there, so I think the problem is probably happening in the Params > Interceptor. > > I tried changing our List<> variable to an Array[5000], and then it populated > everything correctly. So my best guess is that the interceptor is > initializing a list with a size of 256, but then it doesn’t expand the size > correctly once the initial list has filled up. > > This same code was working fine a year or so ago, but I’m not sure when it > stopped working or what version of struts we were on at the time. > > Thanks for your help, > Allan Jackson > University of Kansas --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
